When shopping for refrigeration valves, pumps, and line components, the first fork is whether you need new tubing or access to an existing line. These four components cover both sides: a 50-foot copper coil, a 100-foot ice-maker water line, and two adjustable piercing valves. Prices run from $8.89 to $70.99. The right pick comes down to the job in front of you-connecting a new line, extending a supply tube, or adding a service port to a sealed system.
Quick take
If a sealed A/C or refrigeration line needs a service port, look at the BPV31 Bullet Piercing Valve or the A1 Refrigerator Line Tap Access Piercing Valve. If you are building a fresh small-diameter line, the 50-foot copper coil is made for the refrigerant side. If the task is feeding an ice maker, the IMT14100 tube gives you 100 continuous feet of supply line. Match the component to the fluid side: refrigerant goes through copper or a service valve; water goes through plastic supply tube.

Product notes
Copper Tubing 1/8 In OD X 50Ft Refrigeration Copper Tubing
The Copper Tubing 1/8 In OD X 50Ft Refrigeration Copper Tubing is a 50-foot coil of 1/8-inch outside-diameter seamless copper. The main reason to go this route is the long, uninterrupted run: 50 feet gives you enough material to route a new narrow refrigeration line without joining sections. The product is specified to the ASTM B280 standard for seamless copper tube, which is the relevant benchmark for this type of refrigeration line. The trade-off is the small diameter. At 1/8-inch OD, this is not a general-purpose water line, and a full coil is much more than a short patch needs. Choose it when the project is a new small-diameter refrigerant line rather than a quick fitting.
IMT14100 Refrigerator Ice Maker Water Line Tubing 1/4 Inch OD
The IMT14100 Refrigerator Ice Maker Water Line Tubing 1/4 Inch OD is a 1/4-inch outside-diameter tube made from linear low-density polyethylene. The feature that makes this line stand out is its length: 1200 inches, or 100 feet, so you can stretch a supply from a distant water source to an ice maker without splicing. The tubing also has a listed maximum pressure of 205 psi, which gives you a concrete pressure ceiling. The catch is that this is plastic supply line, not copper for a sealed refrigerant circuit. It belongs on the water side of an ice maker. If the job is a long fresh-water run to a fridge, this is the one that covers the distance.
A1 Refrigerator Line Tap Access Piercing Valve fits 1/4\" 5/16\" 3/8\" OD Tubing
The A1 Refrigerator Line Tap Access Piercing Valve fits 1/4\", 5/16\", and 3/8\" outside-diameter tubing, covering the common sizes found on small refrigeration and A/C lines. What you gain with this valve is the included hex wrench and the DIY-friendly positioning, so the tightening tool is right there in the package. The model is listed as A1 from A1 Components and weighs 0.17 lb. The drawback is the California Proposition 65 warning attached to the product; you should review that notice before installing. For a straightforward access tap on a narrow line, this valve gives you a more complete hardware kit than a bare service valve alone.
BPV31 Bullet Piercing Valve for A/C Refrigeration Lines. 5/16 - 3/8 - 1/4 in. In
The BPV31 Bullet Piercing Valve for A/C Refrigeration Lines. 5/16 - 3/8 - 1/4 in. In is a bullet-style tap that accepts 1/4-inch, 5/16-inch, and 3/8-inch inlet diameters, so it matches the same size range as the A1 valve. The reason this one earns a look is that it carries the lowest listed price in this group while still giving you three-size access and metal construction. The thing to weigh is the short manufacturer warranty shown for this product, which is only three months. If you want a compact metal service tap and are willing to accept a limited warranty, the BPV31 is the most direct way to add access to an A/C or refrigeration line.
Final recommendation by use case
- For the lowest-cost service access on 1/4\", 5/16\", or 3/8\" A/C lines, start with the BPV31 Bullet Piercing Valve.
- If you want a DIY-oriented tap that includes a hex wrench, the A1 Refrigerator Line Tap Access Piercing Valve is the alternative.
- For a new narrow refrigerant line, the Copper Tubing 1/8 In OD X 50Ft is the right material.
- For a long ice-maker supply run, the IMT14100 Refrigerator Ice Maker Water Line Tubing gives you the most continuous length.
When the task is sealed-system service, a piercing valve is the fast route. When the task is a new line or a long water run, choose the tubing that matches the fluid side.
